Inhabits the intertidal zone of rivers and estuaries (Ref. 101380). Also in mangrove estuaries where it is often associated with the air roots of mangrove trees, coastal rocks and stones (Ref. 101381). Often seen attached to the stilt roots of the red mangrove Rhizophora spp., fringing lagoons and estuaries (Ref. 106421). Also found on low subtidal level attached to rocks, shells, or stones on muddy sand bottoms (Ref. 109255).
